process-exit-actions

Arguments:
process

Returns the exit-actions for process, which must
be an instance of mp:process. The value is a list
whose elements are of the form (function
. arguments). When the process finishes, either normally or
via an unwinding kill, it executes the actions by applying the
functions to their argument lists. You can use setf to change the value though it is more
normal to push additional
actions onto it.
